Do-it-yourself kitchen knife made of cardboard on the Do It Yourself portal

Swiss knife model

You can also make a Swiss knife out of paper. It received this name because it was used as a weapon in the Swiss army. It was red. The finished craft can be used in gameplay or presented as an interesting gift to fans of such weapons.

The design of a knife is carried out using the following tools and materials:

cardboard, preferably white;
a simple pencil;
bolt with nut or rivet;
glue and needle.

What materials will be needed

Before you start practicing origami, you should collect the necessary materials and tools. The most important tool in origami is your hands, but paper and a few simple tools will come in handy to help you create beautiful masterpieces (Figure 2).

Making a dagger from paper using this technique is done without glue, and the finished product looks like a real edged weapon.

When choosing material for origami, you should consider the following recommendations:

The best paper for origami is office paper, which is thick and not too smooth. It is well suited for modular origami and will hold its shape wonderfully.
Colored office sheets are painted on both sides and will not turn white on the folds when folded.
To create simple models, small sheets of paper (square-shaped) intended for notes are suitable.
Note blocks (sticky notes) can also be used to create your origami masterpieces.

Figure 2. Materials required for work
Also, when creating any paper product, you can use the following tools: glue, scissors, paints, cutter, pencil, rulers (triangle, protractor).

Types, features and drawings for DIY knives

How to make a paper cube: origami and diagram
There are many types of knives that have different applications. The blade’s design, shape, material for manufacturing, strength characteristics and much more depend on the scope of application of the blade. Let's consider the main types and sketches of knives for self-production, depending on their purpose.

There are a lot of types of knives, so it’s difficult to choose the right one. PHOTO:

Hunting knives

This is probably the most ancient and sought-after type of bladed weapon. Hunting knives were used to fight wild animals and cut up prey. High demands have always been placed on them:

Pirate knife

A pirate knife for a children's game or theatrical performance is best made from cardboard.

On a cardboard sheet of the required size, draw with a pencil the shape of a pirate's bladed weapon and cut it out. Then attach the cut out sample, trace it on the cardboard and cut it out again. Make sure all edges match.

After the 2 parts are ready, you need to glue them and paint them. Or you can wrap the blade with shiny foil and cover the handle with colored paper.

Manufacturing technology

Using origami techniques, you can create many interesting things or objects that will be identical in identity to their originals. Folding a paper knife without glue using the origami technique is not difficult (Figure 3).

A dagger made of such material is not a bladed weapon and will not cause harm to human health, but can only serve as an element of costume decoration or as part of children's games.

You can make a dagger with your own hands using this origami technology:

Fold the sheet in half diagonally (you should get a triangle with a right angle). For this purpose, it is better to use thick office paper.
Fold the resulting triangle in half again.
We expand the resulting model to its initial state and bend the corners of the sheet to the central vertical line.
Fold the workpiece in half and take into account the center line.
We stuff the protruding ends of the workpiece (on either side) into the pocket and begin to form the tip of the blade. We press our fingers on one side of the figure (located from the pyramid) and hold it, after which it will be seen that the blade of the dagger has become voluminous.
We take another sheet, roll it into a tube, and insert it into the pocket to a depth of about 6 cm.
Using your fingers or any flat object, level the edges of the tube (about 5 cm) and turn the workpiece to the side 90 degrees.
We repeat the action of wrapping three times until a round shape of the handle is formed.
The ends of the product must be tucked into the first fold and a little drop of glue to fix the dagger, or use tape to secure it.

If you want to make a paper bladed weapon heavier, you can put pebbles or coins in the blade.

Kunai Dagger

One of the serious paper products can be called a Kunai knife. The paper art of origami is used to construct it. Before you begin the manufacturing process, you need to find two landscape sheets and several sheets of colored paper.

How to make a ninja knife from paper:

Kunai Dagger

We take a landscape sheet as a basis, fold it and get a triangular shape. Fold the resulting triangle in half, and then unfold the workpiece to its original position.
We wrap the corners to the center line and fold the craft in half. Next, we have protruding ends, which we bend into the resulting pockets and thus form the blade of our future craft.
Pressing the edge in the shape of a pyramid with your fingers, we lift the paper a little to achieve volume. We take a second sheet of paper, roll it into a tube with a small diameter and insert the blade five centimeters deep.
Next, use your fingers or a sharp object to level the edge of the tube and repeat folding several more times. A handle with a tip should form. At the end, we fix the craft.

Many people want to make the craft heavier and put a coin or pebble in the middle. This is how a ninja knife is made, there are many more options for making knives. Many are trying to learn how to make karambit from paper, we will also tell you about that, but a little later.

Knife with hook

The hook knife is designed for gutting thanks to its hook on the blade. We will now look at how you can make such a knife at home.

Print and cut out the knife template. On drawing paper, outline its fragments (separately the blade and separately 2 sides of the handle).
Blade templates need to be cut out in 15 pieces, and handles - 10 pieces on each side.
Using glue, we glue all layers of the blade and 10 layers of the handle.
Then we glue the handle onto the base of our blade.
Glue sandpaper to the knife blade and cover the handle with colored paper.

Video lesson

In this tutorial you will see how to make a simple origami knife that is quite easy to fold.

The Japanese knife-making specialist has demonstrated his unusual art more than once. He made knives from chocolate, foil, pasta, fish and even water. Therefore, a knife made from a cardboard box turned out to be quite simple for him.

First, he soaked the cardboard with water, folded it, squeezed out the entire flag, flattened it and tried to make this sheet as thin, dense and hard as possible. The master did not use any glue or resin other than what was already contained in the layers of cardboard. Of course, the result is a fairly sharp blade, but you definitely shouldn’t throw it in the dishwasher.

Types of balisongs

Nowadays you can find many models of balisongs on sale. They come in both classic and unusual blade shapes. The famous knife fighting master Jeff Imada divides them into four groups, we will add two more:

Large balisongs up to 29 centimeters long; Medium up to 24 centimeters long; Small up to 19; Ultra small, the length of which does not exceed 9 centimeters; Butterfly training knife, it can be either with a blunt blade or with a comb-shaped blade; Knives with exotic blades type.

The last point should be considered as collectible knives, although there are also quite working combat options.

Instructions: Cardboard butterfly knife

Another common model, the so-called “butterfly”, can be made entirely from cardboard or from cardboard and foam board. The peculiarity of this knife is that it can be opened or closed, with one movement of the hand turning the blade case into a handle and back.

1. Download and print the template. You will find it here.

2. Lay the paper blade pieces onto a sheet of corrugated cardboard and cut out all the pieces. For the handle body, regular thick cardboard is used.

3. Glue two narrow strips of corrugated cardboard onto the inner surface of the handle halves, as shown in the photo. Don't miss this detail, otherwise your knife blade will not be able to move freely.

4. Next, glue foam cardboard strips on top of them, and the second half of the handle on top. Do not apply glue to the entire inner surface of the case!

5. Now pierce the bottom of the blade with a toothpick. Make sure that it protrudes about 1cm on both sides of the cardboard (cut off the excess) and secure the structure with hot glue.

6. All that remains is to connect the handle and blade. To do this, insert the latter into the body, close it, and pierce all three parts with toothpicks at the base - one on each side.

7. Make sure the blade comes out of the handle freely and secure the toothpicks to the outside of the body with hot glue.

The knife is ready!

Paper cutting. Community 365 review.

Today I will talk about such a difficult at first glance type of creativity as paper cutting. This art supposedly originated in China and in the local language it sounds like “jianzhi”

. In China it has several directions: “chuan-hua”

or “window flowers” (emerged from the tradition of decorating the windows of houses for the spring festival) and
“si-hua”
(holiday decorations, ritual objects and wishes for all occasions). Subsequently, the art of carving spread throughout the world, acquiring its own characteristics in each country.

Traditional Chinese work was done exclusively with scissors

, but now there is an easier way - cutting with a breadboard knife.

This is what we will talk about. If you wish, you can also work with a regular stationery knife with a retractable blade, but this option is not very convenient when working with small parts.

I'll start with the materials you'll need for the job:

1. Paper

. In fact, it can be absolutely anyone who is more comfortable in their work. I prefer smooth thick paper, about 200 g/m. My Birdie book is cut out of smooth white paper 220 or 240 g/m. For those in Moscow or St. Petersburg, I can recommend the store “World of Paper”, also known as “Double V”. On their website they also write that there are branches in Samara, Tver, Chelyabinsk, Novosibirsk, Krasnoyarsk, Krasnodar, Rostov-on-Don, Kyiv and Almaty. But I wasn’t there, I don’t know what or how. So: in this store you can choose paper for almost any application. In the hall there are racks with samples, which indicate the name, density, color, embossing and sheet size. Prices are indicated in catalogs on the tables. Before the holidays, prices there were much lower than in art stores; now, most likely, they have also risen, but in any case, it turns out to be somewhat more profitable and they usually have more choice. Well, if you just want to try the technique without spending extra money, you can always learn how to cut on regular Whatman paper.

2. Knives.

They come in several types. The most common breadboard knives

They are a handle with a collet clamp that secures a replaceable blade. There are now a lot of companies producing such knives. I use a set of knives from an unknown manufacturer:

The small box contains three handles with blades, a number of additional blades on a magnetic strip and tweezers. Previously, I worked only with the thinnest knife, but after working with it for a long time, my fingers begin to hurt. Now I mostly work with a medium knife. It has a heavier handle, it fits more comfortably in the hand and does not cause any unpleasant sensations during operation. I almost never use the largest knife; its handle is not very comfortable for me, but it all depends on personal preference.

In terms of prices: one simple knife is quite suitable for testing, now there is a huge selection, prices start from about 100 rubles. (information about Moscow, prices of art stores).

The second type of knives is a prototype one with a hinged blade.

. In the photo he is black. This is an art knife from Mr. Painter." Overall, it’s a pretty convenient thing, but you need to get used to it to work with it. If before this you cut with a regular breadboard knife, you will have to adapt to the rotating head of this knife

But if you learn to work with it correctly, it can greatly facilitate the process - you will not need to constantly turn the blade; the hinge allows you to do this by changing the tilt of the handle. It is also worth noting that the blades of a hinged knife differ from conventional collet blades.

They are narrower and smaller in size. I have not yet purchased additional blades; the set with this knife includes 10 additional blades. This is quite enough for the first time.

Option: Cardboard Swiss Army Knife that folds

If you want to surprise amateurs, then make a folding Swiss knife with a scarlet handle. Such models have long symbolized the Swiss army. So let's get started:

Download the Swiss Army knife template and print it. Using a pencil, carefully transfer each detail onto thick white cardboard paper and cut out all the elements. We take three parts - the tip, the saw and the back body part, put them on top of each other and pierce them with a “gypsy” needle or awl. We insert a button into the hole, which can be purchased at an office supply store.

Apply a thin ball of adhesive base to the elements circled with a red dotted line. But be careful that the adhesive base does not get on the part of the knife, which will then become retractable. Fold the outer piece onto the back piece so that they match along the contour.

Now the design. You can put an “engraved” inscription on the tip.

Now a souvenir in the form of a fake knife from Switzerland is ready.

Falchion

By the way, the drawing for the falchion is also quite complicated. Photos are small in size so that it is convenient for you to view them from your mobile phone. To view and print the actual dimensions of the drawings, you need to download the archive from Yandex Disk.

One day I wanted to buy a butterfly knife, also known as a “balisong”. But then I decided that I shouldn’t spend money, but make this instrument myself. So I set about searching for instructions on how to assemble it on the World Wide Web. There were a lot of such manuals, but most of them were descriptions of cardboard crafts and models made from ice cream sticks. In fact, it was not easy to find useful material, and because of this, it was decided that in the end I myself would post on the Internet my version of how to make a butterfly knife with my own hands.

Note to our craftsmen. We invite you to visit the Domarket chain of stores, where you will find a wide range of goods for the whole family and household goods at excellent prices.

Blueprint: Karambit knife

Before you begin, take drawing paper, scissors, glue, a stationery knife, and a simple pencil.

Print the drawing.
Cut out all the details of the drawing and trace them on drawing paper (base 11 times, handle 12 times).
Cut out all the outlined parts.
Glue all the parts of the bases and handles and place them under the press.
Take one of the sides of the handles and glue it to the knife.
Close with another handle coated with glue.

Advice! Paint the karambit knife, let it dry and coat it with colorless varnish.

Useful tips

You can also make an original karambit knife from paper (Figure 5). Its design is even simpler than making a dagger using the origami technique.

Figure 5. Drawing and photo of paper karambit

To do this, you need to take the finished drawing, cut out two of its parts and trace them on thick paper. In total, you need to make 11 blanks for the knife itself, and 12 blanks for the handle. We cut out all the circled blanks and glue them together. After this, we place the blanks under the press, and glue two blanks of handles to it. When the structure has hardened, it can be painted and varnished. You will find more detailed instructions for making an original paper dagger in the video.
